In May 2009, I wrote a PACE assembler and simulator, and brought up the FIG-Forth implementation for the PACE, originally by David Kilbridge.
I typed in both the source and object code from the published listing, and corrected all of my typographical errors such that the object code output by my assembler matched the object code from the published listing, with the exception of automatically generated indirect words, which my assembler generated in a different order as compared to the original National Semiconductor assembler. Any remaining typographical errors are most likely in the comments.
In the the process of getting it working on the simulator, I found and fixed a bug in the U/ word.
Scans of the original published FIG-Forth Implementations, including that for the PACE, may be found at http://www.forth.org/fig-forth/contents.html.
